Conservation of EnergyKaitlyn, Hannah, and Nicole• Did the total amount of money change?

Conservation of EnergyWhen does a roller coaster have most of its energy as GPE?When is KE greatest?

A B

Calculating Spring Potential EnergySpring Potential Energy – the internal energy of a spring due to its compression or strength; SPE = 1/2kx2

k – spring constant; a spring that is difficult to compress or stretch will have a higher spring constant

What Do You Think Now?How does a roller coaster get to its highest point?

Does it cost more to lift the roller coaster if it is full of people?
